Service or Services?

"There is no more train service to A, B and C," announced the station master.

Immediately, it struck me as to whether the sentence is grammatically correct. Do we define the train service as singular or plural? There are three lines which are affected. So should the plural form be used?

I brought this up to Norman and Nic. And we all have differing views. Ultimately,the question boils down to how we define the word "service". Is it an all-encompassing word which takes into account that service is not countable? Or do we define it by the number of routes?

Imposing this idea onto life, how do we define happiness? It is subjective.

As long as people understand the English that you are speaking, all is well.

As long as we smile and exude happiness, all is well.
